Sticking the eggshell membrane to your face will give you a feeling of contraction. When it is dry and torn off, the acne will be sucked out, then wash your face with ice water to shrink pores, and finally apply cucumber to your face and replenish water. Do it often. This is not a problem that can be solved in a day or two. I tried it, and it worked well. Don't be impatient, eat more fruits and vegetables to help digestion, drink more water to make your skin tender, go to bed early and get up early. Persistence is victory, don't be discouraged!
